Hey Tobias,
oh jea you are right ??
The plugin was “Advanced Access Manager”.
I have deinstalled that plugin, and reinstalled it and did the same with “TablePress”.
Sadly i dont get access to the point where i can reactivate the “TablePress” Navigation point because it is not in the List to reactivate it.
Can you help me or should i contact the person from Advanced Access Manager?
PS: Your Plugin is G R E A T ! ! !
